Topic "OBSERVING THE EARLY UNIVERSE WITH COBE"
Detailed studies of the spectrum of the cosmic microwave
background using the COsmic Background Explorer satellite launched in
1989 allow one to study energy release later than 1 year after the Big
Bang. Studies of the temperature fluctuations around the sky allow one
to see structures as they existed 300,000 years after the Big Bang; but
these structures were formed less than 1 nanosecond after the Big Bang
and provide us with our earliest observed datum about the history of
the Universe.
